Why does my heating and cooling make loud noises?
The heating and cooling system can make a variety of noises. Some of these noises are normal and others signal a more serious condition. For the majority of homeowners, these noises are harmless but do affect home comfort and peace of mind.
How do these noises come about? As the heating and cooling system works, parts vibrate and move. Over time, small screws, nuts, bolts and other pieces come undone. As the heating and cooling continues to work, these pieces tick, click, thump and buzz.
While these noises are nothing serious, if you do hear these sounds, it’s probably time for HVAC maintenance. Heating and cooling maintenance gives your HVAC technician the chance to make these small fixes and scout for bigger problems before they happen.
